The jumping spider family (Salticidae) contains more than 500 described genera and over 5,000 species, making it the largest family of spiders with about 13% of all species (Peng et al., 2002). Jumping spiders have good vision and use it for hunting and navigating. They are capable of jumping from place to place, secured by a silk tether. Both their book lungs and the tracheal system are well-developed, as they depend on both systems (bimodal breathing).

The Sydney funnelweb spider, Atrax robustus, is an Australian funnelweb spider found primarily around Sydney, Australia. It is a notoriously aggressive species and is among the deadliest spiders in the world.

Sydney funnelwebs are medium-to-large in size, with body lengths ranging from 2 cm to 7 cm (0.9" to 3"). They are glossy and darkly coloured, ranging from blue-black to black to brown or dark plum coloured. The carapace covering the cephalothorax is almost hairless and so appears smooth and glossy.

Male and female Argiope

The genus Argiope includes rather large and spectacular spiders that have often a strikingly coloured abdomen. These are well distributed throughout the world, and most countries in temperate or warmer climates have one or more species, which look similar.

In North America, Argiope aurantia is commonly known as the "black and yellow garden spider", or "writing spider," because of the similarity of the web stabilimenta to writing.

A falcon (fÉ”lkÉ™n or fælkÉ™n) is any species of raptor in the genus Falco. The word comes from their Latin name falco, related to Latin falx ("sickle") because of the shape of these birds' wings.

The Secretary Bird, Sagittarius serpentarius, is a large, mostly terrestrial bird of prey. Endemic to Africa, it is usually found in the open grasslands and savannah of the sub-Sahara.[2] Although a member of the order Accipitriformes, which also includes many other diurnal raptors such as kites, buzzards, vultures, and harriers, it is so distinctive that it was given its own family, Sagittariidae.

Vultures are scavenging birds, feeding mostly on the carcasses of dead animals. Vultures are found on every continent except Antarctica and Oceania.

A particular characteristic of many vultures is a bald head, devoid of feathers. Research has shown that the bare skin may play an important role in thermoregulation.[1]

Osprey with fishThe Osprey (Pandion haliaetus), sometimes known as the sea hawk, is a diurnal, fish-eating bird of prey. It is a large raptor, reaching 60 centimeters (24 in) in length with a 1.8 metre (6 ft) wingspan. It is brown on the upperparts and predominantly greyish on the head and underparts, with a black eye patch and wings.

Birds of prey are birds that hunt for food primarily on the wing, using their keen senses, especially vision. Their talons and beaks tend to be relatively large, powerful and adapted for tearing and/or piercing flesh. In most cases, the females are considerably larger than the males. The term "raptor" is derived from the Latin word "rapere" and may refer informally to all birds of prey, or specifically to the diurnal group.[1]
